阅读更多关于 Spring AMQP and ShutdownSignalException

问题 I have an AMQP Project with Spring AMQP. The RabbitMQ Server is not mine, so I have no control over it. When my application starts, it makes a private response queue like this: @Bean(name="myAnonymousResponseQueue") public Queue myAnonymousResponseQueue() { Queue q = myAmqpAdmin().declareQueue(); return q; } And I have a SimpleMessageListenerContariner like this: @Bean public SimpleMessageListenerContainer myResponseMessageListenerContainer() { SimpleMessageListenerContainer container = new

AMQP Stuck waiting for ACK

问题 I am using https://github.com/Azure/azure-event-hubs/tree/master/c library which uses AMQP 1.0 protocol. When I send the first message to event hub via send project it gets stuck waiting for ACK. On my home PC it works fine. On my other PCs, even on Azure Virtual Machine - which is Windows Server 2012, it just waits for ACK in infinite loop. How can I solve this? 来源： https://stackoverflow.com/questions/40133998/amqp-stuck-waiting-for-ack

Consume only N messages from RabbitMQ with react\stomp, ack them separately and then exit

阅读更多关于 Consume only N messages from RabbitMQ with react\stomp, ack them separately and then exit

The main reason for that is we dont want to have long running consumers and we want to restart them after N messages. 回答1: You can set a prefetch count for a destination: The prefetch count
